WOGene expression is the fundamental process by which the information encoded in a gene’s DNA is used to create a functional protein. This process occurs in two main steps: transcription and translation.
1. Transcription (DNA to mRNA)
• The enzyme RNA polymerase copies the genetic information from the DNA sequence of a gene into a molecule of messenger RNA (mRNA).
• It does this by pairing complementary RNA nucleotides with the DNA template strand.
• A key difference is that Uracil (U) is used in the mRNA instead of the DNA base Thymine (T).
2. Translation (mRNA to Protein)
• The mRNA then moves to a ribosome.
• Here, transfer RNA (tRNA) molecules read the mRNA’s code in sequences of three nucleotides called codons.
• Each tRNA brings the specific, corresponding amino acid for its codon.
• These amino acids are linked together in a specific order to form a long chain, known as a polypeptide chain.
• Finally, the polypeptide chain folds into a functional, three-dimensional protein that performs various cellular functions.
This entire process ensures that the genetic blueprint is accurately converted into the machinery necessary for life.
